The purpose of this study was to evaluate the height of workbench in dental lab for ergonomic body type which dental technicians are suitable and suggest to effective improvement of workspace. For this purpose, we measured the height, weight, body sizes of total 77 junior majoring in dental laboratory science where they study school located in Gyeonggi and Chungcheong area and we research uncomfortable body type when they had a clinical training. For comparative analysis we had visited 15 dental lab and 2 dental lab of general hospital and we had measured the height of workbench and desk including chair and then We had statistical analysis measured value. Especially we analyzed the important factor causing inconvenience for work environment. As a result, we had examined, we found following results The sand table was the most uncomfortable equipment, when they have clinical training. There is no correlation between sexual characteristics of junior in college and selection of uncomfortable equipment. It is reasonable to assume that sand table which is lower than recommended height brings out inconvenience. It is analyzed that the optimum height of sand table in dental lab for junior in college is lower than the recommended height. The optimum height of sand table in dental lab has deviation according to height of junior in college. The height of worktable in dental lab was lower than recommended height. The recommended range could not apply to posture of dental technician with different height uniformly.

Background: Factors affecting oral function include tooth number, oral muscle strength, and oral diseases. This study aimed to investigate the relationship among oral environment, muscle, and microbiology. Methods: Fifty-six elderly individuals in a day care center were included in the study. The survey regarding tongue and lip muscle strength and oral microorganisms was conducted from November to December 2018. Results: Tongue and lip muscle strength were greater in men than women (p>0.05). Tongue muscle strength was greater in the ${\leq}80-year-old$ group ($34.94{\pm}9.85$) than the ${\geq}90-year-old$ group ($25.57{\pm}7.54$) (p<0.05). Tongue muscle strength and lip muscle strength were greater in the ${\geq}15$ functional teeth group ($34.08{\pm}9.31$ and $9.25{\pm}1.63$, respectively) than in the <15 functional teeth group ($28.08{\pm}7.53$ and $7.76{\pm}1.51$, respectively) (p<0.05). Age was significantly correlated with functional tooth number, denture use, and tongue muscle strength. The number of functional teeth was positively correlated with tongue muscle strength, lip muscle strength, and oral microorganisms. Denture use was negatively correlated with tongue and lip muscle strength. Tongue muscle strength was significantly correlated with lip muscle strength. The number of Eubacterium nodatum was higher in men than women. The number of Parvimonas micra and Enterococcus faecalis was higher in the groups with ${\geq}15$ functional teeth, denture use, and greater tongue and lip muscle strength. The number of Lactobacillus casei was higher in the group that uses dentures and with greater tongue strength. Conclusion: Oral microbiology is more important in oral environment and management than oral muscle function. The correlation between oral muscle and oral microorganism requires further study. Therefore, oral care training should be conducted to improve the oral care practice of elderly individuals, maintain oral health through oral care, and prevent the decrease in saliva secretion by aging.

PURPOSE: This study sought to investigate the change in the satisfaction levels of healthcare students regarding clinical practice before and after the coronavirus disease 19 (COVID-19) outbreak. METHODS: This was a longitudinal survey using a structured questionnaire. The first survey was conducted before the COVID-19 outbreak in April 2018, and the second survey was conducted after the outbreak from May to June 2022. The questionnaire used before and after COVID-19 had the same content and was categorized into the following six factors to determine clinical practice satisfaction: practice guidance, practice environment, practice time, practice evaluation, interpersonal relationships, and effectiveness of practice. Before the COVID-19 pandemic, a total of 153 healthcare students (average age: 22.43 ± 1.47 years old), participated from 4 departments: nursing, physical therapy, occupational therapy, and dental hygiene. After COVID-19, 84 students (average age: 22.75 ± 2.87 years old), from the physical therapy, occupational therapy, nursing, and dental hygiene departments participated in the survey. RESULTS: Clinical practice satisfaction was evaluated considering the factors of practical guidance, practice environment, practice time, interpersonal relationships, and practical effects. It was observed that the satisfaction with clinical practice increased in nursing, physical therapy, occupational therapy, and dental hygiene students after COVID-19 compared to the situation before the outbreak. There was no difference seen in the practice time and practice evaluation factors in the occupational therapy department and in the practice time factor in the dental hygiene department before and after COVID. CONCLUSION: In clinical practice under the extremely constrained circumstances imposed by the COVID-19 pandemic, it seems that the emotional internal response is greater, and the satisfaction with clinical practice appears to be relatively higher than before the outbreak.

The target of study are selected form 7 junior health college students and colleges are located in around seoul form 14 junior health college throughout the nation. The questionnaries were distributed between 24th Feb to 30th July in 1997 to the 100 dental technicians who finished clinical practice and entered profession in 1997. All collected data were analysed by using SPSS/PC, Technical Statistic, One-Way ANOVA, Ttest, Person Correnlation Coefficient, Chrobach Alpha Coefficient and the result of the study is follow. 1) The satisfaction degree were classificated as 7 aspect and overall average score was 3.042. During that period satisfaction of personal relation aspect(M=3.737) shows highest level. Satsfiaction of clinical parctice(M=3.571) shows as second, Satisfiaction of environment(M=3.028), Satisfaction of guidance(M=2.915), satisfaction of subject are ordered of their scores. According to above study satisfaction's degree of subject show lowest level. 2) According to the result of verification of study. general character of student and satisfiaction degree has not much relation with sex, location of college, religion, period for enrolling college, teaching method of clinical practice. But the result show similar relation with following items. Satisfaction if subject and satisfaction of clinical practice(P=0.000), place of clinical practice and satisfaction of clinical practice(P=0.002), Academic record of college and satisfaction of clinical practice(P=0.000). 3) The relation of satisfaction(Subject, method of teaching, environment, period, rating, personal relation) of clinical practice and age of investigation's target Older student show higher satisfaction(P=0.040). Also method of teaching, environments, period, rating, personal relation has similarities with satisfaction. Therefore student who has higher satisfaction of clinical practice they also have higher rate for subject, environment, period, personal relation. 4) The result fo investigation, most interesting subject was crown & bridge and most difficult factor was too many simple-works to the student. One of ideal factor was discussing with counselor before they choose place for clinical practice. Third grade and first semester is most efficient time for clinical practice and 8 week is proper period for clinical practice. Clinical practice is absilutory mecessary and we find out most student rated positively. However we need more specific study about satisfcation of each subject. Because it shows lowest level and we need more pay attention for planning of clinical practice.

Many patients with mental retardation need extensive dental treatment because they have much difficulty in maintaining their oral hygiene. However, because they are not cooperative and not manageable, they require physical restraints, drug induced sedation or general anesthesia. General anesthesia is useful in control of the patients who cannot be treated in other ways. Additionally, general anesthesia provides more safe environment for medically compromised patients. And medical treatment can be provided simultaneously under general anesthesia. Furthermore, almost all treatment can be provided without visiting several times. This case reports of periodontal, restorative and ophthalmological treatment of patient with mental retardation under general anesthesia.

The purpose of this study was to obtain the basic information for the improvement of dental environment by investigating the presence of methicillin- or vancomycin-resistant Staphylococcus aureus (MRSA or VRSA) isolated from dental health care workers (DHCWs) and environment of the Chosun University Dental Hospital (CUDH) and a private dental clinic (control group). Staphylococcus aureus (S. aureus) was isolated from anterior nares of 42 DHCWS and 38 sites, unit chairss, x-ray devices, computers, etc., at 10 departments of the CUDH and 20 DHCWs and 11 sites at the private dental clinic. S. aureus was isolated on mannitol salt agar plate and confirmed by PCR with S. aureus species-specific primer. Antimicrobial susceptibility test of clinical isolates of S. aureus against several antibiotics including methicillin (oxacillin) was performed by investigating minimum inhibitory concentration (MIC) using broth microdilution assay. In addition, PCR was performed to detect the methicillin- or vancomycin-resistant gene. The data showed that one strain of S. aureus was isolated from DHCWs of the CUDH and three strains of S. aureus was isolated from 3 samples of the private dental clinic, respectively. All of the isolates from the CUDH and the private dental clinic had resistance to penicillin G, amoxicillin and vancomycin and susceptibility to oxacillin and ciprofloxacin. The S. aureus strains were already obtained the resistance to penicillin G and amoxicillin. These results suggest that two dental clinics were under relatively safe environment.
